Power Costs The cost of translating photons to electrons and the need to power POTS service limit the use of fiber in the loop to places that have a lot of traffic. As the costs of the equipment go down, the fiber will reach farther into the outside plant. Until then, a good compromise that gains many of the operations advantages of a pure fiber solution is using coaxial cable from the fiber node to the residence. With fiber in place, SDH can be used to carry voice, data, and video. 9 The SDH/SONET overhead channels could be converted to ATM cells and mixed with all other ATM cells to use the bandwidth more efficiently.

If standards cannot be achieved and it becomes necessary for the carrier to own the equipment and rent it to the customer, the problem becomes even more complicated. This was done once before in the telephone industry. When local telephone companies used to rent telephone sets, they needed a system to keep track of them and other customer premises equipment in order to charge each month for each item. This tracking was done with paper records. Development of automated “left-in” administration computer systems stopped in 1984 when local companies no longer rented the customer premises equipment.

So it might be a good idea to agree not to send more than perhaps 100 at a time and await a postcard acknowledging successful receipt before sending others. The Transmission Control Protocol does all these things to deliver data reliably over the basic Internet Protocol service. That's really all there is to it. Of course, I have left out some important other details such as routing (how do packets get to where they are supposed to go) and naming conventions.
